Identification
A long white day in an uptrend is followed by a relatively small black day
that gaps in the direction of the trend. The next two days continue the
brief pullback and are small days that stay within the range of the first
day. The fifth day is a long white day that closes above the close of the
first day and continues the uptrend.

The Psychology
In an uptrend, a long white day is followed by a brief pullback (preferably
on lightish volume). The fifth day simply continues the trend. The brief
pullback is nothing more than a few days off for the bulls.
